Title: Interlock switch baseplate assembly
Inventor: MAYO STEPHEN K
IPC: H01H3/16
Filed: 1988-03-24
Granted: 1992-02-11
Abstract: IMPROVED INTERLOCK SWITCH BASEPLATE ASSEMBLY                 ABSTRACT OF THE DISCLOSURE An interlock switch assembly is disclosed having a unitary baseplate with relatively few moving parts and making use of conventional low cost miniature switches, each positively located and retained with respect to the baseplate.  First and second actuators convert, respectively, linear motion of first and second operators into rotary motion to actuate the miniature switches.  Switch actuation is prevented unless the properly timed motion of both operators is received by the actuators.  A third actuator receives the motion of the first operator and actuates a third switch in response thereto.  In one embodiment, the third actuator is prevented from actuating the third switch until after actuation of the first and second switches.  In one embodiment, a primary interlock switch is the first switch deactuated and is preferably capable of interrupting power to the microwave energy source when the door is opened before the cooking cycle is completed.  In this embodiment, the next switch to be deactuated is a logic monitor switch, followed by release of a secondary interlock switch acting as a backup to the primary interlock switch.  Finally, an interlock monitor switch is deactuated preferably placing a short circuit across the load side of a power circuit of the switch assembly in order to blow a fuse in the event of a "failed-closed" condition of both the primary and secondary interlock switches in the deactuated state.

Title: Fluid heater using pulsating combustion
Inventor: CHATO JOHN D
IPC: F23C6/02
Filed: 1988-05-09
Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE      A fluid container includes at least one pulsating combustion unit which defines an elongate exhaust passageway between two substantially parallel plates, along with an elongate combustion chamber communicating with the exhaust passageways.  Two end caps close the ends of the elongate passageway and the elongate chamber.  Inlets are provided for admitting a combustible fuel mixture to the combustion chamber, and spark plugs provide ignition means to ignite the mixture.  The unit is disposed in the container in such a way that a major part of each of the plates defining the exhaust passageway is in direct contact with the fluid.  By initiating and sustaining pulsating combustion in the combustion chamber, a high-amplitude shockwave passes through the exhaust gases, which effectively "scrubs" away the gaseous, laminar surface film on the plates, thus enhancing heat transfer through the plates.

Title: Guide device for automated guided vehicle
Inventor: NISHIKAWA SHOJI
IPC: B62D1/28
Filed: 1988-06-02
Granted: 1992-11-17
Abstract: ABSTRACT   A guide device for an A.G.V. in which a magnetic field generated around a guide cable is detected by a pair of detection coils at both sides of the guide cable, and wheels are steered and driven in accordance with the detected output from the detection coils.  A pair of detection coils are arranged to follow the movement of the wheels to be steered in such a manner that the detection coils are disposed away from each other at a predetermined distance from the guide cable when the A.G.V. runs a straight portion of a course, while the detection coils are positioned closer to the guide cable when the A.G.V. runs a curved portion.  As a result, when the A.G.V. runs the straight portion, the sensitivity with respect to the deviation between the detection coils is kept low so that the carrier can run smoothly.  When the A.G.V. runs a curved portion, the sensitivity with respect to the deviation between the detection coils is increased.  Consequently, operating performance such as high speed operating performance and the minimum turning diameter can be improved.

Title: Call screening in a public telephone station
Inventor: ARBABZADAH MOHAMMAD A
IPC: H04M1/677
Filed: 1988-09-23
Granted: 1992-03-17
Abstract: CALL SCREENING IN A PUBLIC TELEPHONE STATION         Abstract Control equipment employed in a customer-owned public telephone station prevents a user from making unauthorized telephone calls in a telephone system. Operating under the control of a computer in the station, the control equipment employs a call screening process which restricts the telephone numbers a user can dial to those numbers preselected by a station owner. The telephone numbers are categorized in multiple but distinct groups, each of which represents a specific class of telephone call. The control equipment is responsive to momentary loop breaks occurring on tip and ring lines connecting the station to a central office, and to a loop break provided by the central office which reflects that the far end party has disconnected. The control equipment is also responsive to scheduled as well as unscheduled receipt of dial tone. Thecombination of the call screening process along with the ongoing loop break and dial tone detection and analysis conveniently provides the desired protection sothat the user will be properly charged for telephone calls made from the station. The restrictions incorporated in the station for obtaining this protection are applied with minimal inconvenience for the legitimate user.

Granted: 1992-07-14
Abstract: Patent Title SOUND ATTENUATING LIQUID-GAS SEPARATOR                              Inventor Peter J. Linnert Abstract Sound attenuating liquid-gas separation apparatus includes nested elements which are tuned to abate noise in general and at predetermined frequencies in particular in a screw compressor assembly. The apparatus includes a helical flow path defined internal of an outer shell.  The shell is selectively perforated at its downstream end to allow for the egress of separated oil from it.  The apparatus includes a columnar, open-ended cylindrical member internal of the outer separator shell and a discharge conduit which penetrates both the separator shell and the open end of the columnar cylindrical member disposed within the shell to create the nesting which both contributes to the oil separation process and abates noise.  By selectively dimensioning and therefore "tuning" the nested members in accordance with the characteristics of the particular compressor with which they are used, compressor assembly noise abatement at predetermined frequencies is accomplished.
